Different from those in [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, the work investigated in [7]} is the most relevant work to our study.
[7]} studied a multi-hop energy harvesting cognitive radio network that enjoys only conventional communication. They proposed an algorithm to maximize end-to-end throughput with joint time and power allocations optimization, named JOTPA. As investigated in [7]}, we study a multi-hop network and propose the HBCT algorithm to maximize end-to-end bit delivery through time and power allocation optimization. The difference between JOTPA and HBCT algorithms is that JOTPA is an algorithm that works only in the conventional manner; however, HBCT is a hybrid algorithm that works with both conventional and backscatter manners.
